Uterine cervical cancer Computer-Aided-Diagnosis (CAD) according to this invention consists of a core processing system that automatically analyses data acquired from the uterine cervix and provides tissue and patient diagnosis, as well as adequacy of the examination. The data can include, but is not limited to, color still images or video, reflectance and fluorescence multi-spectral or hyper-spectral imagery, coherent optical tomography imagery, and impedance measurements, taken with and without the use of contrast agents like 3-5% acetic acid, Lugol's iodine, or 5-aminolevulinic acid. The core processing system is based on an open, modular, and feature-based architecture, designed for multi-data, multi-sensor, and multi-feature fusion. The core processing system can be embedded in different CAD system realizations. For example: A CAD system for cervical cancer screening could in a very simple version consist of a hand-held device that only acquires one digital RGB image of the uterine cervix after application of 3-5% acetic acid and provides automatically a patient diagnosis. A CAD system used as a colposcopy adjunct could provide all functions that are related to colposcopy and that can be provided by a computer, from automation of the clinical workflow to automated patient diagnosis and treatment recommendation.

A cervical biopsy instrument that includes a central shaft defining a longitudinal axis and a stop extending laterally from the shaft. The stop typically is formed in substantially the shape of a circle in a plane disposed at substantially right angles to the central axis of the shaft. The instrument also includes an electrode extending from an endocervical portion of the shaft to the stop. The stop may be formed in the shape of a complete circle, or a partial circle. Any free ends are configured to be rounded and extend inwardly toward the shaft or away from the endocervical portion to prevent the presentation of sharp edges or the like which could be caught on irregularities of the uterine cervix. The stop may be affixed to the central shaft along a tangent, or ends of the stop may be affixed to the central shaft. In another embodiment, the stop encircles or partially encircles the shaft, with the shaft extending substantially through the center of the circle. In this embodiment, either one or two electrodes may be provided. Spokes support the stop with respect to the shaft. The spokes may be formed at an acute angle with respect to the shaft to extend away from the shaft toward the endocervical end thereof. These configurations allow the instrument to be rotated in either a clockwise or a counter-clockwise direction about the central axis of the shaft without fear of catching on the uterine cervix. In another aspect of the invention, a marker is provided on the stop to indicate the location of the electrode.
